` COMBUSTIBLE-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 793,443, dated June 27, 1905. Application led May I6, 1903. Serial No. 157,369.

To all whom, t may concern.-

Be it known that I, CHARLES D. HOFFMAN, burner 8 a citizen of the United States, residing at Whitestown, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Combustible-Arresters, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an explosion-arrester in burners; and it consists in the mechanism hereinafter more fully described and claimed. i

The object of my invention is to provide a water seal between the supply-pipe and the burner.

My invention may be used with oil, naphtha, gasolene, benzin, kerosene, gas, and other aurners, where the combustible material is xupplied to the burner through a pipe or pipes, md can only be used where the burning sub- :tance has a less specific gravity than water.

Having in general terms described the pur- )ose and object of my invention, I will now roceed to describe it in reference to the iiglre illustrated in the drawing.

The figure illustrates a vertical section of 1y machine, broken lines indicating parts reloved.

vHaving described my invention with refernce to the ligure in the drawing, I will now roceed to describe the same in detail, in 'hich similar numerals refer to correspond- 1g parts throughout.

The best method I have provided for the se of my invention is illustrated in the figre set out in the drawing.

I provide vertical receptacle 1, which may -ntain combustible oil or other burning subance of lessv specilic gravity than water. I

'nnect receptacle 1 with supply-pipe 2, conolled by the cock 3, which pipe discharges to the water-receptacle 4, which is iilled up line 5, or nearly so, with water, and as the mbustible material of less specific gravity discharged into the water-receptacle 4 at or ar the bottom of the receptacle it rises above le 5 and lls the space 6 above the waterline and passes into burner-pipe 7 through and produces flame 9.

For maintaining the water in water-receptacle 4 at the proper height I provide watersupply pipe 10, controlled by cock 1l, so that by turning water into funnel 12, the stop-cock being in proper position,water may be placed in water-receptacle 4, so as to maintain it at proper height. The burner-pipe 7 opens at 13 just below top of oil or combustible Huid, so that by operating stop-cock 3 the oil or other combustible fluid may be fed into re- 6o ceptacle 4 suiiiciently fast to supply the oil through burner-pipe 7, which is controlled by stop-cock 14. By this arrangement in case of an explosion taking place at the burning-point the iiames cannot be communicated to the supply-tank, the two parts being at all times sealed with a column of water which is of greater specific gravity than the burning iiuids or compounds.

Water-receptacle 4 is glass, so that the water and oil or combustible fluid can always be seen by the operator at a glance, the invention being to maintain above the water-line as small an amount of combustible fluid asV is consistent with the proper operation of the burner, whether it be a single fiame or a series of flames.

For preventing the necessity of breaking the lines of connections I provide in the neck -of water-receptacle4a cork 15, through which 8o all three of the pipes pass, which of course must be made tight.

My invention may be used with any combustible fluid or material where the specific gravity of the burning Huid is less than the specific gravity of water, so that the liuid will always find its level above the water-line, thereby maintaining at all times a water seal in the line of communication-between the fluid-supply pipes and the burner-pipes, so that if an explosion takes place it cannot be communicated to the source of supply of the burning iiui vVariations, in the method of construction may be indefinitely made without departing from the spirit of my invention where a wapreferably made of 7o to permit the removal of the water-receptacle from connection with the other parts, substantially as described.

2. In adevice of the character described, a

receptacle provided with water and a space for combustible material, a supply-reservoir for the combustible material` a burner, a conduit from the supply-reservoir to the water,l

a conduit from the water without the waterchamber and a conduit Jfrom the space in the water-chamber to the burner, the said conduits being each independent of the other and each passing through a common mounting removably seated 1n the Water-chamber, 1n combination, substantially as shown.

In testimony whereof I aiiix my signature in presence of two witnesses.

CHARLES D. HOFFMAN.
